Background

In a virtual machine system created based on kvm (kernel-based virtual machine) -qemu (virtual machine simulator) technology, a qemu process is run for each virtual machine instance. For virtual machines configured in different CPU specifications, threads with the same specification number are created inside qemu to simulate the VCPU (virtual CPU) of the virtual machine.

Embodiments of the present disclosure provide a method of creating a virtual machine in a physical system, the physical system including a plurality of physical nodes, each of the plurality of physical nodes including a plurality of processing resources. The method comprises the following steps: receiving a creation request for creating a virtual machine, the creation request including configuration information of the virtual machine, acquiring allocation information of processing resources of each physical node, determining a target physical node corresponding to the virtual machine based on the allocation information and the configuration information, and creating the virtual machine on the target physical node.

Fig. 1 schematically illustrates an application scenario 100 of a method and apparatus for creating a virtual machine in a physical system according to an embodiment of the present disclosure.

It should be noted that fig. 1 is only an example of an application scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.

As shown in fig. 1, a physical system in an application scenario 100 according to an embodiment of the present disclosure may include a first physical node 110 and a second physical node 120. The physical system in the embodiments of the present disclosure may be, for example, a system of a non-uniform memory access (NUMA) architecture.

The first physical node 110 may include a processing resource pool 111, and the processing resource pool 111 may include a plurality of processing resources therein. The processing resource may be, for example, a CPU core (CPU core) of the physical node. For example, if the CPU of the first physical node 110 has 8 cores, then there are 8 processing resources in the processing resource pool 111 of the first physical node 110.

The second physical node 120 may include a processing resource pool 121, and the processing resource pool 121 may include a plurality of processing resources therein. The processing resource may be, for example, a CPU core (CPU core) of the physical node. For example, if the CPU of the second physical node 120 has 8 cores, then there are 8 processing resources in the processing resource pool 121 of the second physical node 120.

The disclosed embodiments may establish virtual machines in a physical system, for example, virtual machine VNF1 and virtual machine VNF2 are established in first physical node 110. The second physical node 120 has established therein a virtual machine VNF3 and a virtual machine VNF 4. Where each virtual machine has two VCPUs (for example only), each VCPU may be bound to a CPU core in the physical node so that the physical node may provide the computing resources of the CPU for the virtual machine.

Each physical node resource in the physical system of the disclosed embodiments is isolated. That is, the VCPUs of the virtual machines may all be bound to the CPU core of the physical node where the virtual machine is located, and no inter-physical node binding is performed. For example, Vcpu 0 of virtual machine VNF3 may bind with CPU core2 in the second physical node, but be prohibited from binding with CPU core in the first physical node. The scheme for forbidding cross-node binding in the embodiment of the disclosure can avoid the problem of poor memory access performance caused by cross-node.

According to embodiments of the present disclosure, one or more CPU cores in the processing resource pool (e.g., core1 in processing resource pool 111) may provide computing resources for the virtualization platform, and the portion of the CPU cores may not be bound to any virtual machine. Other CPU cores in the processing resource pool (e.g., cores 2-8 in the processing resource pool 111) may provide computing resources for the created virtual machine, and the CPU core may be exclusively owned by a virtual machine or shared by multiple virtual machines.

It should be understood that the number of physical nodes, virtual machines, and processing resources (CPU core) in FIG. 1 is merely illustrative. There may be any number of physical nodes, virtual machines, and processing resources (CPU cores), as desired for an implementation.

FIG. 2 schematically illustrates a flow diagram of a method of creating a virtual machine in a physical system, according to an embodiment of the disclosure.

According to embodiments of the present disclosure, a physical system may include a plurality of physical nodes, each of which may include a plurality of processing resources. For example, a physical node with a CPU having 8 cores may include 8 processing resources, and a physical node with a CPU having 4 cores may include 4 processing resources.

As shown in fig. 2, the method includes operations S201 to S204.

In operation S201, a creation request for creating a virtual machine is received, where the creation request includes configuration information of the virtual machine.

According to an embodiment of the present disclosure, the configuration information may be, for example, a configuration specification of the virtual machine. For example, configuration specifications for CPU, memory, disk, etc.

For example, the configuration information may further include the amount of processing resources of the physical node that the virtual machine needs to occupy and the binding relationship with the processing resources. For example, a virtual machine needs to occupy and bind exclusively with N processing resources, where N is an integer greater than 1. For example, a virtual machine needs to configure 2 VCPUs, each VCPU needs to have processing resources of one physical node bound exclusively.

In operation S202, allocation information of processing resources of each physical node is acquired.

According to an embodiment of the present disclosure, acquiring allocation information of processing resources of each physical node includes: and acquiring the quantity of the processing resources of the physical node, which can be used for binding with the virtual machine, and the current binding state of the processing resources. For example, the number of processing resources available for binding with the virtual machine in the physical node 1 is 4 (CPU core1 to CPU core6), where the current binding state of the CPU core1 is exclusive binding with other virtual machines, the current binding state of the CPU core2 is shared binding with other virtual machines, the current binding state of the CPU core3 is shared binding with other virtual machines, and the current binding state of the CPU core4 is idle.

In operation S203, a target physical node corresponding to the virtual machine is determined based on the allocation information and the configuration information.

According to the embodiment of the disclosure, a plurality of physical nodes in a physical system can be traversed in sequence, whether the current physical node meets the requirement for creating the virtual machine is determined, if yes, the current physical node is determined to be a target physical node, otherwise, whether the next physical node meets the requirement is continuously determined until all the physical nodes in the physical system are traversed.

In the embodiment of the present disclosure, when a virtual machine needs to be exclusively bound to N processing resources, a target physical node that meets a creation requirement needs to have at least M processing resources that are not configured as non-exclusive bound processing resources, where M is an integer greater than or equal to N.

For example, if the virtual machine needs to be bound exclusively with 2 processing resources, at least 2 processing resources in the target physical node are in a non-exclusive bound state.

According to an embodiment of the present disclosure, M is greater than N in a case where at least one of the M processing resources is in a shared bonded state.

For example, the virtual machine needs to be exclusively bound to 2 processing resources, and at least one processing resource in the physical node is in the shared bound state, so that the virtual machine can become the target physical node only when at least 3 processing resources in the physical node are in the non-exclusive bound state. Because, at least one processing resource in the physical node needs to be in a shared bound state to provide computing resources for the shared bound virtual machine.

According to the embodiment of the disclosure, the target processing resource in the target physical node corresponding to the virtual machine can be determined based on the allocation information and the configuration information.

For example, the configuration information is that the virtual machine needs to be bound exclusively with 2 processing resources. The allocation information includes: the physical node 1 includes a CPU core1 in a shared bound state and a CPU core2 in an idle state, and the physical node 2 includes a CPU core1 in an exclusive bound state, a CPU core2 and a CPU core3 in a shared bound state, and a CPU core4 in an idle state. It may be determined that the target physical node corresponding to the virtual machine is physical node 2 and the target processing resources corresponding to the virtual machine are CPU core3 and CPU core4 of physical node 2.

In operation S204, a virtual machine is created on the target physical node.

According to the embodiment of the disclosure, a virtual machine can be created on the determined target physical node, and the virtual machine is bound with the target processing resource, so as to provide the computing resource for the virtual machine.

In the embodiment of the present disclosure, when other virtual machines have been bound to the target physical node in a shared binding manner, the other virtual machines are migrated to other non-exclusively bound processing resources in the target physical node.

For example, continuing the above example, the configuration information is that the virtual machine needs to be bound exclusively with 2 processing resources. The allocation information includes the CPU core1 in the exclusive bound state, the CPU cores 2 and 3 in the shared bound state, and the CPU core4 in the idle state in the physical node 2. It may be determined that the target physical node corresponding to the virtual machine is physical node 2 and the target processing resources corresponding to the virtual machine are CPU core3 and CPU core4 of physical node 2. If the CPU core3 is already in the shared binding state with other virtual machines, the other virtual machines sharing the CPU core3 may be migrated to the CPU core2 of the physical node 2, so that the other virtual machines share the CPU core2, and the CPU core2 provides computing resources for the other virtual machines.

The embodiment of the disclosure can evenly schedule the virtual machine to be created to run on which physical node through the processing resource allocation information of each physical node and the configuration information of the virtual machine. The scheduling in advance can avoid that the virtual machine is failed to be created and the resources are rolled back to cause unnecessary resource waste because the physical nodes do not have enough bound processing resources during the creation.

In the embodiment of the disclosure, the processing resources in each physical node are isolated, and the virtual machine does not need to bind the processing resources across the nodes, so that the problem of poor memory access performance caused by node crossing can be avoided.

The embodiment of the disclosure can allow the virtual machine to exclusively or share the binding processing resource, and can provide more choices for the tenant, the exclusive binding processing resource can improve the processing performance of the virtual machine, and the shared binding processing resource can improve the number of the created virtual machines.
